2 Claims.

This invention relates to an improved partition for houses and other buildings and particularly to an improved foundation core and overlying plaster layer partition structure.

An object is to provide an improved partition of the character described which is inexpensive, which is of strong rugged construction, which may be rapidly erected and which occupies a minimum of space. A further object is to provide such a partition which does not require the use of steel supports or steel core sheets, critical materials subject to priority under present conditions but which employs materials readily available. More particularily an object is to provide a partition comprising a foundation consisting of a plurality of wall sheets of composition board or the like secured together in such a multi-ply relationship and having plaster so associated therewith as to produce a strong, sturdy partition.

This partition is particularly suitable for use in low cost housing structures which demand inexpensive partitions capable of being rapidly erected and utilizing a minimum of critical materials.

The improved partition preferably comprises a core formed of a plurality of fiat sheets of suitable composition material arranged in edge to edge relationship and secured together. The sheet sections which constitute the core are preferably arranged in two plies and so secured together that the sheets of one ply are connected to the sheets of the other ply and the several sheets of each ply are connected to each other through the sheets of the other ply. Plaster is associated with the core as an integral layer extending over the outer surface of the several sheets of each ply and, as illustrated in the embodiment shown in the drawings, the two plaster layers are integrally connected through the core sheets.

Other objects, advantages and meritorious features of this invention will more fully appear from the following description, appended claims and accompanying drawings, wherein:

Fig. 1 is an elevation of a partition embodying my invention, partly broken away and partly in section,

Fig. 2 is a cross-sectional View taken on line 22 of Fig. 1,

Fig. 3 is a cross-sectional view taken on line 3--3 of Fig. 1,

embodying my invention, taken on the same line as Fig. 2, showing the type of base illustrated in my co-pending application, Serial No. 398,822,

Figs. 6 and 7 are details, respectively, showing specific types of connecting clips utilized to secure the core sheets together.

In Figs. land 2 the partition is shown as comprising a core structure made up of a plurality of sections of suitable sheet material such as composition fiber board, gypsum board or the like arranged edge to edge and secured together. Such sheet material comes in standard sizes which are convenient for handling and I prefer to arrange the several sections in two plies as shown in Figs. 1 and 2. These sheets are indicated by the numeral ID. The sheets of the two plies are arranged back to back. The sheets of one ply aredisposed to break the joints formed between the sheets of the other ply as illustrated.

in Figs. 1 and 2.

Preferably these structural sheets are provided with perforations l2.

through the sheets in one ply will register with the perforations through the sheets in the other ply even though thesections are so disposed as.

to break the joints.

The sheets of one ply are secured to the: sheets of the other ply by suitable means such as; wire ties I4, Figs. 1 and 2, or the tie clips l6 and I8, Figs. 6 and 7. The securing means not only connects the sections of one ply to the sheet. sections of the other ply but connects the several. sheet sections of each ply together through the sheet sections of the other ply due to the overlapping relationship as illustrated in Fig. 2.

This partition core may be secured along its top margin to the ceiling by an angular strip of metal lath 20 attached in any suitable manner to the ceiling 22 and attached to the core structure by a wire tie 24 extending through spaced apertures I2. The floor structure might be secured by wood strips such as shown along the floor. The floor is indicated at 25 and two wooden nailing strips are indicated at 26. These nailing strips 26 are arranged on opposite sides of the two ply core and are secured together by a connecting staple 28, which staple extends through an aperture l2 in the core sheet, as shown in Fig. 2.

There is provided along the floor a channel footing strip 30 which is shaped to provide a mid-rib 32, as illustrated in Figs. 2 and 4. This channel may be secured by nails 34 or the like to the floor 24 and the mid-rib 32 received with- These are arranged in standard pattern whereby the perforations in the joint between the two plies of the core as shown in Fig. 2. The nailing strips are seated within the channel upon opposite sides of the core structure and as shown in Fig. 2.

Plaster is applied to each outer surface of the core. As shown in Figs. 1, 2, 3 and 4, an integral layer of plaster 36 extends over the outer surface of each ply of the core and extends as at 38 through the apertures l2 so that the two layers of plaster are connected integrally together through the core sheets, forming a unitary partition structure or bridging of the plaster through the several perforations of the core sheets and the securing of the sheet sections of one ply to the sheet sections of the other ply and the securing of the several sheets of each ply together, all contributing to provide a partition structure which is particularly rigid and sturdy. The securing means either in the form of wire ties or clips which extend through the apertures in the core sheets are immobilized within the plaster that also extends through such apertures as shown in the figures of the drawings.

In Fig. 3 there is shown a section through the door jamb illustrated in Fig. 1. The door jamb itself is indicated as 40. It is attached to the rough buck 42 and nailing strips '44 extend along opposite sides of the core sheets l and are nailed as shown to the rough buck 42. Door casing members 46 extend along and are nailed to the rough buck or nailing strips. The wire tie l4 extends around the rough buck 42 and the nailing strips 44 through the apertures in the core sheets.

Fig. illustrates that type of metal base which forms the basis of my application, Serial No.

398,822, and in which interlocking channel base members 48 and 50 are disposed upon the opposite sides of the core sheets l0 underneath the plaster 36 as illustrated in Fig. 5. The base member 48 is secured to the floor as shown and extends underneath the core sheets. Base member 50 is interlocked with the base member 48 and is also tied thereto by tie clips 52,

In the type of base shown in Fig. 2 heretofore discussed in connection with the discussion of securing the core sheets to the floor, there is provided base members 54 arranged upon opposite sides of the partition along the floor and nailed or otherwise secured to the nailing strips 26 as shown in Fig. 2 to complete the finish along the floor. These base members overlie the nailing strips 26 and extend over the joint formed between these strips and the plaster layer, all as illustrated.

As heretofore stated, the tie clips [-6 and [8 of Figs. 6 and 7 respectively are suitable for use to secure the two plies IU of the core together instead of the wire ties l4 shown in Fig. 2. Tie clip I6 is a round wire spring clip shaped to grip the two plies l0 together. Tie clip 18 is a flat sheet metal spring clip provided with teeth I9 adapted to engage in the core sheet.

What I claim is:

1. A partition consisting of a foundation core constructed of a plurality of fiat sections of composition sheet material arranged in edge abutting relationship and in two over-lapping plies with the sheet sections which constitute one-ply breaking the joints of the sheet sections which constitute the other ply, the sheet sections of the two plies provided with a plurality of registering apertures, connecting means extending through registering apertures of over-lapping plies and through apertures in edge abutting sections holding over-lapping sections of the two plies tightly together and holding abutting sections in a ply tightly together against relative displacement, a plaster coating adhesively secured as an outer layer over the two opposed surfaces of said foundation core, said plaster extending through the registering apertures of the sections constituting the two plies connecting the two layers of plaster together forming an integral structure, the connecting plaster ties through the two plies being sufiiciently numerous and of sufiicient combined cross sectional area to render the partition relatively rigid and self -supporting.

2. The invention as defined in claim numbered 1 characterized in that said connecting means which extends through registering apertures of the two plies and connects said plies together is of sufficiently smaller cross sectional dimension than the cross sectional dimension of the registering apertures through which said means extend that connecting plaster ties extend through the same apertures as said connecting means.
